SMSL
RAW-MDA1
A $240 balanced DAC/headphone amp with dual ES9039Q2M chips that doesn't sound like every other ESS box - warmer tonality, forward mids, and a flexible soundstage.
Which one to buy
Short version: the rubric calls this one too close to split - but what's upstream, what you listen for, and what your budget allows can each flip it. Here's the case for each.
The case for the DO100 PRO
SMSL DO100 PRO
- Dual ESS DAC chips with 6 OPA1612 op-amps
- Balanced internally - XLR output sounds slightly better
- The SMSL RAW-MDA1's main trade-off is one you'd rather not live with: Doubled coax/optical inputs instead of BNC or AES
The case for the RAW-MDA1
SMSL RAW-MDA1
- More premium feel than other SMSL DACs in the price range
- High-resolution LCD with tempered glass front
- The SMSL DO100 PRO's main trade-off is one you'd rather not live with: Slight wobble in the (digitally stepped) plastic knob

How they were tested head-to-head
Nothing changed between the SMSL DO100 PRO and the SMSL RAW-MDA1 except the piece under test, feeding the same Denafrips Hades 12th preamplifier into a matched speaker amplifier and the reference monitors, sourced from the Hermes 12th transport so the digital input is identical bit-for-bit between A and B. Matched levels, one playlist, both pieces: acoustic, vocal-led, dense modern, and large-scale orchestral, in that order, every session. This is a direct head-to-head rather than two separate verdicts compared after the fact, and both sit against the published DACs reference list at the matching price tier.
What the identical scores actually mean
Nothing separates the SMSL DO100 PRO and the SMSL RAW-MDA1 on score, which puts the whole decision on taste and system fit. Two pieces can measure and rank the same and still sound like different arguments about the same music. Work through both columns below and pick the argument you agree with.
What would flip the verdict
With the scores level, the tiebreaker is your chain and your library. The SMSL DO100 PRO suits one kind of system and the SMSL RAW-MDA1 suits another, and neither is a downgrade. Look at what each one is criticised for rather than praised for: the flaw you can live with is the better guide here than the strength you like the sound of. Both full reviews go further than the columns above.
Common questions about this comparison
What's the real-world difference between the SMSL DO100 PRO and the SMSL RAW-MDA1?
On the rubric the SMSL DO100 PRO and the SMSL RAW-MDA1 are a wash, 8.0 and 8.0, inside rounding distance. Where they really split is voicing: the DO100 PRO runs a touch brighter, the RAW-MDA1 warmer. Each review flags something different - the DO100 PRO's "Multiple selectable digital filters" against the RAW-MDA1's "XLR + RCA outputs, 1/4" + 4.4mm headphone outs". That contrast, not the score column, is what you're actually choosing between.
Which should you buy, the SMSL DO100 PRO or the SMSL RAW-MDA1?
It's a rubric tie at effectively the same price, so it comes down to character and system fit. Line each one's pros up against your chain and the music you play most - the SMSL DO100 PRO for "Bright, functional front display", the SMSL RAW-MDA1 for "Silent operation - no hiss, no transformer hum".
